Re: [yt-users] installation issues

Sorry to revive an old thread, but just to clarify: bitbucket recently disabled the use of CNAMES (the hg.yt-project.org URL is an example of this) due to security concerns. Since CNAME urls rely on SSL authentication from the site associate with the CNAME, rather than bitbucket, it was possible to do a man-in-the-middle attack on code downloads through these URLs. The net effect is that hg.yt-project.org is deprecated and URLs using it will no longer work. Instead, use https://bitbucket.org/yt_analysis/yt. -Nathan On Fri, Jul 17, 2015 at 3:54 PM, Shankar Agarwal wrote:

It’s unfortunate that the 3.1 link is wrong (since that’s the current stable version), but any link for version 2.x should not be trusted.

What operating system are you trying to install yt on?

Hi Cameron,

There are many yt versions that point to:

wget http://hg.yt-project.org/yt/raw/stable/doc/install_script.sh

http://yt-project.org/docs/2.5/orientation/installing.html http://yt-project.org/docs/3.1/installing.html

You are right that the above downloads an index.html.

Anyway, the new link you gave me, works well (although I had to use --no-check-certificate): wget http://bitbucket.org/yt_analysis/yt/raw/stable/doc/install_script.sh --no-check-certificate

However, installation failed with a pyexpat error:
